## When it is useful

Use chDB DataStore as a pandas-compatible API backed by in-process ClickHouse. Change import pandas as pd to import chdb.datastore as pd. Not raw SQL (chdb-sql) and not a ClickHouse server. Python 3.9+, pip install chdb.

## The Catch

In-process pandas twin, not a ClickHouse server. OSS/chDB is 0 USD. ClickHouse Cloud is a trial plus 300 USD credits, not a hobby plan. Do not invent a 30-day window. Distinct from chdb-sql.
